Connector Housing Guide Structure for L-Shaped Wire Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors face difficulties in assembling terminal-attached electric wires due to the intersecting orientation of the electric wire and terminal, making it challenging to insert them into the housing.
Innovation Solution
A connector design featuring a housing with an inclined guide surface that separates from the inner surface of the front portion towards the compartment, allowing the terminal to be guided and inserted without hitting the inner surface, facilitating smooth assembly by providing a path for the electric wire to intersect the fitting direction.

Engineering Contradiction Analysis
1Volume of moving object
If the terminal and electric wire are arranged in an intersecting orientation (L-shape), then the connector achieves compact space utilization and proper terminal orientation for mating connection, but the assembly process becomes difficult as the terminal-attached electric wire cannot be easily inserted into the housing through the electric wire insertion hole
Solution Approach 1:
The guide portion is pre-formed within the housing with an inclined surface that preliminarily guides the terminal-attached electric wire during insertion. This preliminary guiding action prepares the wire's path before it reaches the final position, making the assembly process easier despite the intersecting orientation requirement
Solution Approach 2:
The guide portion acts as an intermediary element between the electric wire insertion hole and the internal space. The inclined surface of the guide portion mediates the transition of the wire from the insertion hole into the internal space, facilitating smooth insertion by preventing direct contact with the inner surface of the front surface portion

AI summary
A connector includes: a plurality of terminal-attached electric wires in each of which a terminal is attached to an electric wire in a direction intersecting an extending direction of the electric wire; and a housing including a plurality of compartments that holds the terminal in a fitting direction, and a plurality of electric wire insertion portions that is provided penetrating a side wall portion and configured to extract the electric wire in the plurality of terminal-attached electric wires from an internal space in a direction intersecting the fitting direction. The housing has guide portions provided between individual accommodating regions for the plurality of terminal-attached electric wires arrayed and accommodated in the internal space. The guide portion has an inclined surface inclined with respect to the extending direction of the electric wire.
